Therapeutic Hypothermia After the Return of Spontaneous Circulation

Status Terminated

Clinical Trial Summary

The purpose of this study is to determine if induced therapeutic hypothermia (ITH) in the pre-hospital setting of a four county emergency medical system (EMS) that serves both urban and rural communities improves meaningful survival from medical cardiac arrest.

Clinical Trial Description

Induction of therapeutic hypothermia after return of spontaneous circulation (ROSC) in medical cardiac arrest is increasingly becoming the standard of care in the hospital setting. Several studies, including two sentinel research papers in the New England Journal of Medicine, show improved neurologic outcome with induced therapeutic hypothermia (ITH). 4, 5 This research led to a class IIa recommendation by the American Heart Association for ITH after ROSC in V-Fib arrest and a class IIb recommendation after ROSC in all other classes of medial cardiac arrest.6

The role of ITH in the pre-hospital setting is less clear. Studies currently exist that both show a benefit and fail to support improved outcomes.7-9 It has been suggested that the short transport times in most urban EMS systems might be part of the reason that some studies have failed to find benefit of ITH in the pre-hospital setting.

This is a prospective, randomized controlled trial involving all patients transported by CCEMS who have ROSC after a medical cardiac arrest and who are transported to a hospital that can continue ITH for 24 hours. All comatose patients who meet inclusion criteria will be randomized to either ITH in addition to continued treatment under standing protocols or regular care without ITH. Assignment to the two treatment arms will be done using the EMS number which is generated when the ambulance is dispatched to a call. Even numbered patients will have continued standard therapy while odd numbered patients will receive ITH. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
